T=time
when the piano dropped at t=0, its velocity also equals 0
but at t(3)=32(3)=96
the piano is falling at 96fps
Answer:
640 people
Explanation:
480 people = 75 %
x people = 100%
480 : x = 75 : 100
75 x = 48,000
x = 48,000 : 75
x = 640
y=3 when x=15
this is because we can set up a ratio of when x/15 and set it equal to 6/30 and divide them, solve for x.
